WHat i did was:

-restore 2.2 nandroid backup

-flashed 2.2 fixed sbf so i could keep downgradability...

Now when i tried to go back to 2.1 eclair version 2.21

-i flashed 2.21 blur full sbf

and now i have black screen as if downgrading wasn't possible...

What options do i have ?
[Defy General] shad0wboss:
NO HELP? am i the only one with this problem here?

ANother question i had if there's a way of downgrading kernel? because i've experimented this. On kernel 2.6.29, the multi touch works fine but on kernel 2.6.32, multi touch is buggy, way buggy...
[Defy General] Jygar:
I'm guessing your stuck on 3x roms. So your going to need to see if you can reflash the fixed rom and try downgrading again.

If not that fixed rom wasn't fixed.

[Defy General] shad0wboss:
Thanks for THE reply...so now what i can do is flash full sbf (3.4.2.145) which is same version as my earliest fixed sbf, restore nand backup of 2.2 then flash the FIXED sbf CEE one (3.4.2.155) and then try downgrading? would this work?

EDIT: Walter79's sbf's are messed up..i used his fixed sbf version...didn't try CEE one tho
[Defy General] dj_destruction:
Did you find a solution to downgrading i to did the same thing.
[Defy General] step0011:
errrm...

righto after reading that post again, i've had to change this :| I have had a similar problem myself, but i did manage to resolve it with 2 nights after work of swearing, redbull binges and many failed attempts :| I finally somehow managed to get Pays-ROM to load :| hope you get it sorted though :)
[Defy General] shad0wboss:
Im on a fixed sbf again..but my prob is to go back to 2.1

I hv restored 2.2 nand nd flashed 2.2 fixed cee rom..if i flash a full 2.1 sbf..wud it work?
[Defy General] kashavsehra:
From what I know, if you have flashed 2.51 or higher full sbf (non fixed) then you cannot go back down to 2.21.

However if you have flashed 2.51 or higher with the system and CDT code groups removed (i.e. fixed SBF), then you should be able to go back to 2.21 just by flashing the complete 2.21 sbf.

DO NOT flash a full sbf 3.4.2.145, because that will upgrade the CGs that prevent downgrade.
[Defy General] shad0wboss:
What if i flashed 3.4.2-145 (full sbf) and then restored 2.2 froyo nand and then flashed a 3.4.2-155 fixed SBF, now if i flash a full 2.1 sbf, would it work?
[Defy General] kashavsehra:
No, because once you flash any FULL sbf that is greater than 2.21 then you flash the parts of the ROM that are non-downgradeable. Once those partitons have been flashed then you cannot downgrade. That is why the FIXED sbf's should have those partitions removed.
[Defy General] kashavsehra:
For your information, the detailed investigation around these non-downgradeble code groups is in this thread:

http://xdaforums.com/showthread.php?t=945035

Some very useful information in there, and they summarise that once you flash Version 2 Code Groups, you cannot go back down to Version 1 code groups.
[Defy General] shad0wboss:
Well, i did flash a fixed version of 2.2 sbf and then flashed 2.1 full sbf but that didn't work out and the screen went black...so i flashed 3.4.2-145 full so that atleast i could use my phone but it was a deblur version and i have no contacts...can't import contacts from sim either...so i just want to go back to 2.1 and then give my phone back to motorola...isn't there ANY way to remove those CG's off the rom you're on at the moment`?
[Defy General] zyxwvut:
as far as anyone here understands it, NO Can't be done
[Defy General] danxj3:
Defy to Bravo

Has anyone tried and tested the Defy ROMS (such as PaYs or JBoogie's) on the Motorola Bravo (MB520)?

I would really like to take the plunge, but I've read Bravo users have bricked trying Defy ROMS?
[Defy General] shad0wboss:
Just dumb to try one phone's firmware on anothers. It is just like installing mac software onto windows
[Defy General] polaris441:
I believe the only to go back to 2.1 is to restore the nandroid backup of 2.1.

there are a few thread posting stock nandroid backup of 2.1 (except it's already rooted).

you have to flash also bootonly sbf based on the same version.

then you can manually remove superuser.apk and su manually using adb shell.
[Defy General] Jokerchris2000:
Did someone acutally used this method and was succesful? I have downloaded a stock nandroid and the related bootonly sbf. Furthermore i have the related full sbf file if i need it.

So you think its probably possible to put the nandroid on the sdcard, go to clockwork, wipe everything and then restore the nandroid. Afterwards i think it would be the best to remove the battery, put it back in and boot directly into the bootloader and from there flash the bootonly via rsdlite.

Im kind of scared to give it a try. What if something goes wrong? Can i go back to my last 3.4.x ROM?

Cu
[Defy General] shad0wboss:
I've done this on 3.4.2.xxx version (full sbf flashed). What happens is that it goes to M screen and then reboot, then goes to M screen and reboots...this goes on and on but i haven't tried flashing bootonly. I don't know what can happen if i flash that but what i know is that you atleast DONT get a black screen, it does show M logo...
[Defy General] nolimitzz:
my phone came with 2.54 preinstalled i understand i cant get to 2.21. the question is, if i flash full sbf (not fixed) of 3.4.2 , can i get back to my stock 2.54?

thanks!

edit:

after some research, i will lose downgrade-ability. smg versions of 3.4.2 are +1 higher than my 2.54

hey guys i'am currently using hyperdroid cm7v1.0.2 on hd2.every time there's a new version of this rom,i'am doing a clean install i.e from task29 which erases all my

data.can anyone tell me how to update the rom using the cwm or rom manager without a clean install.

p.s: and one more thing is,will updating removes my old version? or will it be installed on the extra space?
[HD2 Android Q&A, Help & Troubleshooting and Genera] Richy99:
select install zip from card, find the zip file and install it
[HD2 Android Q&A, Help & Troubleshooting and Genera] richiegopal:
thankyou...!very much richy99...and what a coincidence..we both have the same name!
[HD2 Android Q&A, Help & Troubleshooting and Genera] Skellyyy:
You do know you don't have to Task29 for every install? If you're using the same Rom just updating, just flash it. Unless the dev says otherwise. If you're installing a different ROM just wipe data and flash the new ROM. :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] CStites:
When I go through ROM manager and download SONOFSKYWALKER3, where do I go from there to install the rom? I couldn't find it on my SD so not sure when I go through recovery mode.

Hey Guys, i'm new here and would like to know what the best OS for the HD2 is (in your opinions).

After the default Win 6.5 i tried Android and i liked it very much.

So what do you Guys use, and like most ?

[HD2 General] Mister B:
WM6.5.x Energy ROMs, 23699 being my favourite.

Android is a long way off from what I need & comes not even close to custom WM with a user who has educated himself from XDA forums.
[HD2 General] mxxshadow:
thx, did not find it with the keywords "best os"
[HD2 General] Steeltippin:
Android hands down, never liked WINMO ever!
[HD2 General] mxxshadow:
and is there any special build, that is wroth to name it ?
[HD2 General] SpiderVenom:
As far as best os without any issues, as much as it pains me to say so I would have to go with wm6.5 especially if you're just starting out and don't really know how to work on your phone yet. But once you do get a little bit of knowledge behind you I would give it to Android. I've been using NAND as my daily driver for months now
[HD2 General] xlr8me:
Win mo for day to day os and android for weekends on sd card. They are 2 of the best os currently available. Win 6.5 blows anything else for customization. Android comes a close 2nd especially with cyanogen mod.

Love them both long live hd2 :)
[HD2 General] nessqn:
I'm using android as my daily OS now...WM6.5 with energy ROM+CHT is excellent...but i think HD2 runs better with Android,especially GB.
[HD2 General] pmzk:
Android's the best for me :)
[HD2 General] Segnale007:
I didn't know there were still someone using Winmobile on their HD2s.
[HD2 General] Mister B:
Yeh that's what happens when your a fandroid user, can't keep up to date as your platform is a backward muddle & you've slowed your device down by downloading all those two minute developed trashy apps ... lol

Android is ok, have a Desire kicking around but it does not work well as a daily runner for me.

Somewhere between the 2 platforms would be the perfect OS !
[HD2 General] mxxshadow:
ok thx guys, i'm gonna try some android roms
[HD2 General] Segnale007:
Lol u don't even know how good and smooth android works on the HD2, for sure way better than Winmobile does. And what 2 minutes developed trashy apps?? Well at least we have a decent market, look at yours...

Have fun with your Mobile OS supported by none, not even from Microsoft itself...
[HD2 General] Mister B:
It runs no where near as smooth as my current WM ROM setup & I have tried it & also on a native device, won't really notice the difference in term of Microsoft support as we haven't had much help from them over the last 6 years. The amount of quality professional applications for Android is still very limited as for the market, not into that Apple idea, I found all I need via XDA & good web searching & 8 years experience with the platform.

At this current time I could not perform my work tasks via Android hence why my Desire is a toy & paper weight on my desk.

With more platform & professional application support Android will be as good as people boast about at the moment but that takes time & that is why WM still can hold its own ground in the professional user market.
[HD2 General] thunder2007:
androooooooooooid only android
[HD2 General] Segnale007:
Yea, sure, I want u to believe that ... Btw, look at the score above, see the result so far and come back and see it in a couple of days.
[HD2 General] T-Macgnolia:
The score may say andriode but it is not a true reflection of wich OS is better. Win Mo comes out the box more functional an ready for use then Android. Eindows is a stand alone OS where if it was no Lenuix it would be no Android. Everyone likes Android because it runs smooth out the box, but if you use a custom Win Mo ROM it is just as smooth if not smoother than Android.

Now this is partially do to the lack of Microsofts support for Win Mo but tbey have been to busy developing the stupid and redundant WP7 is why. Why is this because people are to lazy to actually spend time to learn how to use Win Mo and how capable and useful it is. Andriod to me feels like a very trimmed down version of Win Mo to me. I mean you have an app tray and thats it, atleast with Win Mo you can organize apps as you want. The Android home screen if cool but install Cookies Home Tab on Win Mo and you have a better home screen then any Android device or ROM. Heck I even prefer the HTC Sense UI in thd stock ROM over Android home screen. I can not no matter how many apps I search for in the Android matket use Android as a literal extension of my home or work PC. As far as apps go hey the apps or out there but once again I go back to people being to lazy to search for them as they are not all in one place. I call that being true open sourced as anyone can make a app for Win Mo. But if Google does .ot like your app it will never be on the market or get pulled from the market. Sure you can still side load it but if it messes up your device there goes your waranty. Besides I have tried a ton of Android apps and what good are apps tbat only do one thing or 500 of the same apps I mean really. Oh and just incase someone wants to mention flash, flash only works on the default Android browser does that really make it flash capable? In short give me a Win Mo and a Android device and I am going with the Win Mo everytime. So have fun with playing with Android while us Win Mo users are actually using or devices to be productive.
[HD2 General] kazzxtrismus:
I agree for

business

winMo is better.. winMo is just as smooth and stable when ROM'd...

with android.. i cant find a CALENDAR (not a stinkin tasker) that will allow notes IN a meeting BEFORE AND AFTER its occurrence.

i cant adjust screen sensitivity

i cant sort my apps

i am limited to # of home screens...etc etc

the market charges for foolish things that should be free like solitaire.

1/2 the games dont work universally or across droid versions (2,2 2,3).

flash is an afterthought.

the office emulation is not very good either.

android will take off when it gets the basics down pat.. in the mean time its a toy like the Iphone... but at least better with the sd card slot
[HD2 General] Mister B:
Good accurate replies, Android hit the big sales by targeting the main Mobile market. Windows was alway first a profesional choice or geeks toy.

Windows is far better in the hands of a capable user who can set it up well & thus that is why I am still using it.
[HD2 General] Segnale007:
Thanks for calling us android users stupid and not even able to set up our own devices. You couldn't have really found a better explanation than this.

[HD2 General] markolino72:
android is a toy

ANDROID IS A TOY WITH UNUNSEFULL 200,000 applications except one, SKYMAP if i use android is only for 1 app

all my android devices got a tragic final end

like my x10 mini (problem hanging a call - wtf for a phone?)

and my eee transformer i throw it to a wall after 2 weeks

honeycomb is a stupid OS without a correct UI and nothing works on it!!!!!

only some games.....

when a see a new release of android im thinking cool!!!! this time they do it, but allways worth, GOOGLE may know that 90 percent of population is stupid and that's their part of the market, I can't believe that big manufacturers can choose a such system fro professional use !!!!!!!!!!! Android is for kids for play angrybirds, thats all

ANDROID IS A BIG BULL****!!!!!!!!!!!!!!!

WP7 drains battery bad!!!! a shame, but is PRO!

WM6 do the job for everithing you want a lot of usefull applications, customizations and etc,etc,etc

HD2 is a very cool device and if you want to use it PROFFESSIONALLY go wm6

i've found a cool custom rom that seems to work well "HD20 v18"

i dont like energy roms !!!!
[HD2 General] hardik1us:

[HD2 General] pauliusval99:
But WHY is android "the best"???

I think it's crap... WinMo WAS the best OS but WinPhone is the best NOW. Android has never been good and won't be something good...

It has NO customization... no, not FEW of customization, it has NO customization!

the ONLY android advantage is games... But who invented that phone is dedicated for games???

If you want a thing for games, buy PSP or whatever you want, but NOT a phone.

Each OS has its own pros and cons

1) WM 6.5 - great on HD2, but no support now and lagging behind technology. It is OS of the past and no one bothers now. Anyone developing apps now ?? Microsoft even doesn't bother about WM 6.5

2) WP7 - I used it and fell in love with it, except the high battery drain. What good a OS, if it doesn't last for a single day? I attribute the battery drain to HD2 WP7 and infact other WP7 has better battery life.. It has one refreshing interface and i score this more than Android

3) Android - Wooo.. Hell lot of support. One won't get this kind of support for any other OS. I can use different ROM daily for the next one month :D I feel the interface is little outdated, but gets the job done...

Whoever has the problem with the interface (Not being able to dial in a single click) can try MIUI Version of Android. It has bought lot of features from iOS and tried to replicate it. I am currently using it and pretty happy with it..

All the best for everyone.. I love my HD2, mainly bcz it supporta multiple flavor of OS and i can choose whatever i need.. duh..

Last but not the least, i wish for iOS port on HD2 ;)

smart or not, it's depend on what are you needed for the phone..

yes indeed, the android has a lot application than winmo...but in the future i don't know..maybe winmo dev will be fix it...:D
[HD2 General] sbhas2k:
Battery life is same in WP7 (7 or 7.5). Can be managed to get little more juice by camera trick and a different soft radio.. But nowhere near Android (if you flash the proper one)
[HD2 General] Armazia:
I have used windows mobile over 5 years now, and I think its the ultimate tweak and usage for a phone, but now a days Android has done a good job too, I use that every day now, and people who say "Android will never be as smooth as wm 6.5" haven't tried Android enough, there are Android roms tweaked till the very end and working very smooth! I've expirienced this in the Rafdroid rom, and the DL Desire rom. Having no problems at all with the phone. I have to admit that its kinda hard to find out how to install some Android roms on it, but after some time you'll get used to it. Oh and when you use Android, make sure to use a propper Micro SD card. I am using a transcend 16 gb Class 6 card, Which is working perfectly fine, and the battery life is in my idea longer in android as in Windows mobile.. But also, Google uses all information we enter in our phone, if they want they can retrieve every password from our devices(on internet ofcourse). Reason? "User Expirience".
[HD2 General] pauliusval99:
prove

yeah yeah... blah blah blah.. PROVE ME!!!

why do you think so?????

everyone says it's very good but NOONE can prove that!!! NOONE have REAL arguments!!!:mad:
[HD2 General] ictimai:
Taking into consideration the CONCRETE requirements:

1.) the smallest battery drain

2.) stability

3.) speed - Android apps run through some sort of VIRTUAL MACHINE, like Java - it wastes CPU resources, doesn't it?

4.) reliability - every hardware function works 100%

5.) issues - e.g. cant' boot without charger pluged in, or can't charge while phone is switched off

...then please tell me an advise: which Android ROM performs better than best cooked modded WindowsMobile ROMs?

are you sure it still holds when best modded WM's ROMs are compared with best Android's ROMs?

This worries me most, Android spies very havily, adding much to Internet data transfer and CPU/RAM utilization - not to mention such "unimportant whims" as our rights to privacy...

To be honest I just wanted to only begin my adventure with Android, and I hoped the modded cooked ROMs with Android for HTC-HD2 were this burden free, i.e. with spying and apps' virtual execution solved by "the open community". However from what I learned here I can see it's not the case, was it? Please, enlighten me...
[HD2 General] dazza9075:
Best is very subjective.....

personally I use WP as my phone OS, why? because its the best phone OS out there, forget all the fluffy stuff around all the OS choices, as a phone, contact list, email display device it is the simplest most efficient device there is bar none, and ill quite happily challenge anyone out there to say otherwise.

as a pocket PC WM wins hands down, there is nothing it cant do and it doesn't sell your soul to the devil. It might be a bit sluggish in a UI sense but in every other way it cant be beaten as a pocket PC

I binned android after a few months because I felt it was trying to be something in the middle, it wanted the ease of use with the PocketPC past and what we ended up with is an OS with an identity crisis, people say its open source so it must be good, well the answer is no, that isn't always true.

What people forget is that no one does anything without getting money for it, so android is free-ish, so how does google make money, if you don't know the answer to that question then your naïve and shouldn't really comment on posts like this., google is making the same mistakes as MS made with WM. The irony is, MS didn't initially make many mistakes with WM, it was the networks and OEMs that shafted WM, but MS took all the heat for it, MSs only failure is that it left development too long and didn't kick the others in to playing nice.

Best OS

I just installed the latest version WM7 and have been playing around a bit because i am not a big fan of the cloud.

there are a few work arounds that help you use the platform an a similar way to WM6.5 (im not sure if this is common knowledge but thought i would pass it on).

If you modify the reg in your PC you can actually see the Phone drive in My Computer (once connected with a USB cable), still its not much use as there is little to play with. The trick is to install windows mobile device centre on the same PC, when you run WMDC there will be a new drive visible in My Computer you can copy what you like to the memory of your phone, Just be carefull where you put it. My Documents is a good place to start and office 2010 files dont need conversion, you can view them straight from your phone.

the reg mod can be found at mobiletechworld.com

[HD2 General] Angelus1984:
I have tried many ROMs and found out that the WP7.5 is the best one. And even the battery life is good now, it lasts me for at least 36-40 hours with calling, lighter internet, 30 min gmail sync...

Very stable, and fast. I found that the Android, even Hyperdroid gets laggy after some time, but WP doesn't. And Android on HD2 has too many problems, every ROM has different issues.

So WP FTW!

Depends on what your looking for it to do best, each have their own BEST functionality and features personally AmeriCanAndroid is what is usually being used for me personally it works perfectly fine, almost hard to believe the phone wasnt made for that rom. Stable/smooth/battery life/features etc.
